EPA Stops Use of Dacthal

The EPA on August 6 issued an emergency order to suspend all registrations of dimethyl tetrachloroterephthalate (DCPA, or Dacthal), a pesticide primarily used on crops. EPA warned in April 2024 that Dacthal could harm the health of people who are exposed to it during normal use. EPA has been investigating this pesticide’s safety, and determined that there was no way to prevent health risks. Dacthal is especially dangerous for pregnant women. It can harm the development of babies during pregnancy and cause low birth weight, impaired brain development, decreased IQ, and impaired motor skills. Because of this, EPA ordered the immediate suspension of sale and use of this pesticide.
